WINDER FOR BRADING MACHNES.

Application fue'august ie, ieee. serial No. 55eme.`

To all whom it maj] concern:

Be it known that I, Anker. PETERsnN, a citizen of the United States of America, and resident of Winthrop, in the county of Suffolk and State of` Massachusetts,- have in vented new and usefulVV Improvements in lliinders for Braiding Machines, of which the following is a specification.

This invention relates to braiding machines of that type employed in the making of thread or cord such for example as is used in sewing shoes and is more specifically concerned with mechanism for drawing off and winding the braid as produced by the machine.

Sewing thread or cord employed in sewing shoes is usuallyl supplied to the trade upon headless spools or quills, the thread mass being of cylindrical form with radial end` faces. It is clear that ,the number of turns of thread upon a cop or thread mass of standard length will differ with the size of the thread, and as any given braiding machine may be called upon at dierent tiniesto makethread of widely different sizes it is necessary to provide for varying the ratio of speeds of the traversing thread guide and the winding spindle, but such variation must not affect the tension vunder which the thread is wound uponV the spindle, although., in order to provide a thread acceptable for sewing, it-should be wound under a tension' as nearly approaching its ultimate strength can safely be maintained.

The principal object of the invention is accordingly to provide a braiding machine having winding mechanism capable of Wind! ing cops,or thread masses under heavy and uniform tension and having provision for changing the number of turns of the braided thread in each of the several layers of the thread mass in accordance with the size of the thread being braided.

1n the accompanying drawings there is shown by way of example an embodiment of means suitable for attaining the above object and in such drawing:

Fig. 1 is a front elevation of the upper part of a braiding machine of well known type showing the Winder mechanism of the present invention applied thereto fFig. 2 is a fragmentary elevation from the left side of Fig. 1 illustrating details of the winder mechanism; and Y Fig. 3 is a vertical cross section on the line 3--3 of Fig. 1.

Referring to the drawings the numeral 1 indicates the stationary cam cylinder ofa braiding machine of that type in which two series of carriers are4 caused to revolve in opposite directions. The carriers of the inner series are not herein illustrated but the rotating support 2 for the other series is shown with the carriers 3 mounted thereon. A frame 4 is mounted upon the base of the machine and bridges the operative parts thereof. This bridge frame has the dpending, centrally disposed member 5 having a clamp for the braiding die at the point G. The member 5V also supports a stub shaft upon which a guide roll 7 turns, and also a shaft 8 uponwhich a takeeup pulley 9 is mounted. At one side ofthe machine a ver-tical shaft 1() is arranged, and this shaft may be driven in any suitable manner from the driving shaft of the machine. The shaft- 1() is provided with a pinion 11 meshing with a gear wheel 12 secured toa shaft 13 having bearings in the frame. Motion is transmitted from the shaft 13 by means of intermeshing gears 14 and 15 to a parallel shaft 16. The shaft 16 is provided with a pinion which meshes with an internal gear (not shown) -upon the inner face of the take-up pulley 9, the arrangement thus far described being substantially like that disclosed in the patent to Peterson 1,413,773, April 25, 1922 to which` patent reference may be had fora more detailed description of these parts. 1f desired the shaft 16 may also drive a measuring wheel 17. l

A sprocket wheel 18 is fixed to the. shaft 16 and a sprocket chain 19 which engages this wheel drives a sprocket wheel 2O mounted to turn freely upon a shaft 21 having bearings in brackets 22 and 23 rising from the bridge frame 4. A clutch member 24 is fast to the shaft 21 and a tension spring 25 surrounding the shaft and adjustable by means of a nut 26 presses the wheel 2O into contact with the clutch member so as normally to impart movement to shaft 21, slight slipping of the parts being permitted however as the diameter of the thread mass increases. rlhe shaft 21 constitutes thewinding spindle and has a member 27 of somewhat larger diameter mounted thereon or forming a part thereof, this member preferably being somewhat resilient and serving for the reception of the quill or other support upon which the thread mass 28 is wound. A pinion 29 is removably keyed te the sha tt Q1 and meshes With a change gear 30 removably keyed to a counter-shatt 3l which is mounted to turn in bearings in a trame comprising;l the spaced arms and 33 and the longitudinally extendingij web member 34. rlhe side members of the 'traine are pivoted to swing' upon a shatt mounted inl hearings at the lower portion ot the bracket 22 and in a bracl-*et respectively. A 1115337 projects 'trom the central pa the web 34. andthe upper end ot link is, pivotally secured to this lng, the lon'er end ot the link passing; through an openi` in a bracket `39 proiectinp; rearwardly 'trl n the member 34. The lower part ot the l' is screw-threaded as shown at l0 and a p ii' of nuts ll and 42 such i threaded portion at the opposite sides of 'h bracket 39. lVith this arrangement th position oit the trame with the shaitt 3l may be accurately adjusted by means ot the nuts stl and 42.

' A pinion 43 is tast to the opposite end ot the shaft 3l and meshes with a pinion 44e tast to a shatt'et *aligned With shatt and mounted to turn in bearings in a pair ot spaced brackets 46. The shatt, 4-5i at that portion which lies intermediate the brackets 46, is provided with a reversely pitched cam groove or Worm t7 ot suitable eontig'uration. A pin enr-ages this: cam groove or Worm, being; carried by a sleeve or mit member t9 't'orminga aart ot the thread guide carriage and which surrounds the threaded portion ot thershatt. This sleeve or nut men'iber is providedzat opposite ends with ears 50, and El respectively which project 'forwardly and into a slot provided betvveen a pair ot ears 52, and 53 which unite the brackets 45. Preferably antifriction means such as the bally bearing ring l-W carried hy a stud projectine,` 'from the nut 49 is arranged to engage one of the bars 52 or to prevent undue Wear and resistance to movement It thread guide trame is pivotally secured to the lugs 50, l by means o't pins such as 5T, This thread `guide 'trame comprises a pair ot spaced lugs 55 and 5G connected by cross bars 58and 58, rThe tree extremities of' the lugs and 5G support a sha'tt upon which a grooved `Qjuide Wheel or roll (30 it mounted to turn.

rlie operation ot the braiding' machine forms braid at the point G. and this bra' after making` several turns about the `guide pulley 7 and the take-up Wheel 9, passes over a pulley (il mounted in a bracket 62 at a suitable elevated point, thence down beneathv the grooved roll titl and then to the Winding thread mass upon the spindle member 27. *During the operation of the braidfiug machine the shaft l() isrrotated, thereby rotatingthe shafty 21, Ey means o't the connections described, the shaft i5 is positively turned in time With the driving of' the winding spindle. The thread guide ear-- is thus caused rapidly to reciprocate bach and 'forth longitudinally ot the spindle thereby laying' the braided thread in close coils and building up a Warp Wound thread ot substantially cylindri al torni hav its coils so disposed that the. thread mass is seit-sostainingl` making a headed spool unnecessary.

,lilith the employment ot the drive above described it is possible by properly tension- 'ng to Wind the 'tl nread under tension, this beingl highly den a thread which is to be used 'for machine sewing as in order to avoit kinkingg ot the thread on its Way to the needle it is necessary that the thread upon the spool er bohbin be Wound under a 'tension apnri'iechingr its ultimate strength. lt it be de- 'ed to braid and Wind thread ot Widely ercnt sir/ies, it is evident that a positive .3 d unfariable drive connection Would pre- 'et the proper laying ot all the di'tlerent '1 y'o 'torni a self-sustaminand compact mass. To permit threads ot 'varying ses 'o he wound, the swinging' traine comthe members 32, 33 is employed.

to suistitite theretor gears oit any other desired e, the adjustability ot the trame perinitti the newgears to be broughtinto proper engagement. By properly selecting l ter et the gears 20 and 30 almost o one e both ot the gears Q9 and 30 and sis ine, dia anv desired' ratio ot rotation ot the spindle the t verse shaft et may be secured. thus peilA ttings; yarn of any ordinary sixe to he "ou d under high tension into a compact mass et a self-sustaining character Without neeessitating;- the dismantling' ot the apparatus and without any substantial loss time.
